LIQUID-FUEL BURNER.

Be it known that we, EDWARD G. MYERS and JAMES W, :CARRJIER, .citizens",,of the United States,Iresidin at Lincolmin the county of Logan andtate'of lllinoighave invented a new Burner, of which fication.

e follow'ing is a specifuel or hydrocarbon'burner's, and aims to providea novel and improved burnerfor coal oil, petroleum, or other liquid fuelIt is the object of the present invention to provide afburner adapted tobe employed in heating for cooking stoves, furnaces, boilers, and thelike, Qr for divers other purposes, which shall ,,be comparativelysimple, durable, and inexpensive inits'construction, as well as beingpractical and ellicient in operation. j

A further object of the present invention is to provide a burnerembodying a co nibination retort and spreader. n connection with asuperheatlng coil and discharge means directed toward the retort andspreader, whereby the spreader will direct the flames toward thesuperheating coil and whereby the spreader, in being heated, willvaporize or gasify the liquid fuel.-

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the precise,embodiment of the invention herein disclosed canbe made within thescope-0f what is claimed Without departing fro nthe spirit of theinvention.

The invention has been illustrated in its preferred embodiment in theaccompanying drawing, wherein I I Figure 1 is a perspective view of theimproved burner, portions being broken away; Fig. 2 is a sectionaldetail of the combination retort and spreader. v

In carrying out the present invention,

there is provided a suitable base 1, upon which is mounted a dischargepipe 2, by means of clamps or other fastening means 3, one end of thepipe 2 having a cap 4 engaged thereon, and the other end of the saidpipe having an elbow 5 attached thereto.

, Attached to the elbow 5 is an upstanding pipe 6, the same being formedinto a horizontally disposed superheatirig coil 7, dis-.

This retort aspread r, mb i a e idiskl ke body 11' hav1ng; ;the coupling socketsuponits top, and extending radiallymtpdij metrically opposite portionsof theretort or: body 11. The bottom of the. retort; and spreader body11. isffiat and unencumbered. and is disposed aboye' thedischergepiper-2* -centrallyof or convolution of the superheating coil 7.

The inner end of the pipe 9 is attached to; one of the coupling socketsl2 and a pipe 13% has one end attached to the other coupling} socket152, and is connected with .avalve' 11,1;

concentric was the ,upper' which is in turn, connected withthefliquidjii,

fuel supply pipe 15. Theliquid fuel, as petroleum, crude oil, or thelike, may-bo l fed either by gravity, or under pressure soz 1s to passthrough the valve, 14, the

valve is open, to the retort A copper or other rod 16 is disposed with;

the super-heating coil 7 or generator- .11

E1 to assist in the eating of the. vapor .or-gas passing thepg through,the discharge pipe 2 being m; vided with an upper aperture 1'? coaxialwith the superheating coil 7, and retort 11, 1 and disposed directlybelow the retort, to,

direct the flames against the bottom of the retort.

An upright draft tube or due 18 has its lower end extending through anopening 19 formed in the base 1 below the vapor pipe 2, the flue 18having diametrically OPPOSltG openings 20 through which the vapor tube.

2 passes, in order that the outlet aperture 17 will be disposedcentrally or axially of the draft-flue. The draft flue is also 00-"axial with the retort or gasifier l1, and its upper end terminatesdirectly below the re-'- tort or gasifier, to provide an annular openingbetween the fine and retort approxi mately in theplane of the upperconvolution' of the superheating coil.

.In operation, when the valve 14 is opened, and the retort or gasifierllis primed in any suitable manner, the vapor or gas will pass throughthe superheating coil and will be discharged from' the pipe 2 throughthe aperture 17, and up thedraft tube 18, so that the flames whenstriking the spreader and retort 11 will continue to heat the same andwill be directed radially from the spreader, so as to heat thesuperheating coil. Thus, the retort 11 serves to gasify or vaporize'thefuel, as well as spreading the flames toward the superheating coil, inorder that the gasv or vapor may be heated to a high temperature, inorder that a most effective combustion of thegas will result to producea maximum lleatihg effect with a minimum expenditure of fuel. It is tobe noted that the body of the retort is dropped below the axis of thepipes passing over the superheating coil, in order to best carry out,the results desired. 1

The draft flue 18 is of advantage, inasmuch as a current of air willflow upwardly therethrough from below the base 1, the air admixing withthe discharged gas or vapor, to support combustion directly below theretort or gasifier. The base 1 is preferably of sufiicient size, to fitover the grate of a fire box, to completely fit in the walls of the firebox, whereby air cannot pass upwardly around the sides of the base, butis constrained to pass upwardly through the flue 18. Thus, the tendencyto cool the superheating coil, will be reduced to a minimum,

. and at the same time, the combustion of the gas will be more thorough.

The present burner may be placed in the fire box of a heating or cookingstove, or may be employed for heating furnaces, If desired, the burnersmay be employed in multiples, for

increasing the heating effect.

retort and spreader, embodying a hollow I disk-like body disposedcentrally within the.

upper convolution of the said coil and having upper coupling sockets,the upper end of the said coil being connected to onesocket, a liquidfuel supply pipe connected to the other socket, a discharge pipeconnected to the lower end of the said coil and extending therebelow,the discharge pipe having an upper aperture directed toward the bottomof the retort and spreader.

2. In a liquid fuel burner, a base, a superheating coil disposedthereabove, a combination retort and spreader disposed centrally withinthe coil and connected to one end thereof, a draft flue commiuiicatingthrough the base and projecting toward the retort and spreader, adischarge pipe mounted upon the base and extending through the draftflue, one end of the discharge pipe being connected to the other endofthe said coil, and the discharge pipe having an aperture within the fluedirected. toward the retort and spreader, and a liquid fuel supply pipeconnected to the retort and spreader.

In testimony that we claim the foregoing as our own, we have heretoailixed our signatures in the presence of two witnesses.
